To all 20 ham it may concern Be it known that I, MARKUM J. E. MAG- NUSSEN, a citizen of the United States, and

a resident of Boise, in the county of Ada and State of Idaho, have invented certain new and useful Improvements in Window Construction, of which the following is a specification.

My invention is an. improvement in window construction, and has for its object, the provision of a simple inexpensive mechanism, for supporting the sashes insuch manner that, they may be swung away from the-casement, to permit access to the sashes for cleaning or the like, or may be moved into normal position with respect to the easement, and when in such position may be raised or lowered in the usual manner.

In the drawings: Figure 1 is a perspective view of the improvement. Fig. 2 is a front view of the same. Fig. 3 is a sec tion on the line 33 of- Fig. 2. Fig. 4 is a side view of a part of the side member of the casement. Fig. 5 is a transverse section of the said member on the line of a pulley.

In the present embodiment of the inven tion, the easement consists of the usual sill I 1, side members 2, and top or cross piece 3. Each of the side members 2 is provided at its lower end with the sash grooves 4, and the parting strip 5, between the grooves, but the said grooves and parting strips at the upper end of the side member are in plates 6 and 7 fitting in a cut away or recessed portion 8 of the side member.

The plate 6 is provided with the continuation of one groove 4. and the plate7 with the continuation of the other, and the recess 8 extends to one side edge of the side member, but not to the other, being separated therefrom by a longitudinal rib 9. A transverse shoulder 10 is provided at the lower end of the recess 8, and the plates 6 and 7 rest at their lower ends on the shoulders, when the said plates are in normal position.

Each pair of plates 6 and 7 is connected at its upper end by a cross piece 6 for the plates 6, and 7 a for the plates 7. The plates and their respective cross pieces form thus a species of frame, and the inner faces of the plates and the cross pieces are grooved to receive the sashes.

The plate 6 is hinged to one end of the Serial No. 110,070.

shoulder, by a hinge 11 and the plate 7 is connected to! the plate 6 at its lower end by a hinge 12. The plates 6 and 7 are thus free to swing outwardly at their upper ends, from the casement, swinging on the hinge 11, and. the plate 7 may swing upwardly at its upper end, away from plate 6, swinging onhinge 12; The inner side edge of frame 77 is provided with a groove 13, for receiving a tongue 14 on the ribor stop 9, to form a tight joint, and the meeting edges of. the frames 6-6? and 77 are rabbeted, as-shownat 15 in Figs. 1 and 3, to break the joint for the same purpose. The continuations 5 of the partingstrips 5 are on-plates 7, so that when the parts are in normal posi tion, the one sash 16 is held between the rib 9 and the parting strip 5 on plate 7 while sash 17 is held between the said strip 5 and a rib 18 on plate 6. By reason of this arrangement, when the frames 66 and 7-7 are swung into the position of Fig. 1, the sash 16 is free to move upwardly away from the strip 5 and when frame 77 is swung upwardly, awayfrom plates 6, the sash 17 is not engaged on its upper szidez, theparting strips 5 being on frame The frames 66 and 77 are locked together at their tops, by means of a latch 19 on the cross piece 6 which engages a pin 20 on the cross piece 7. A look 21 is also provided for holding the frames in the casement. The lock 21 is on the inner face of cross piece 6, and coiiperates with a hasp or catch 22 on the cross member 3 of the casement.

Each of the side members 2 of the casement is pierced by two openings 23 (Fig. 5) and each opening has its inner wall beveled and enlarged, as shown at 24, at the inner end of the opening. A bracket comprising a body 25 and a bearing plate 26 at each end of the body is arranged in each opening 23.

The body 25 is secured in vertical position to the outer wall of the opening, by screws 27 or the like, and the plates 26 eX- tend outwardly beyond the outer face of the said member, at each end of the opening. The outer end 28 of each plate 26 is bent backwardly and inwardly upon the plate, and each of the return portions 28 is provided with an opening for receiving a j ournal pin 29, on a bearing frame 30. Each of the said frames is in the form of a loop with the pins 29 at the ends thereof, and a pulley 31 is journaled in each frame, on a transverse pin 32. Each pulley is thus free to swing on a vertical axis, and is also free to rotate in any position. A cord 33 passes over each pulley, and each cord is provided with a counter weight 34: at its outer end.

Each of the plates 6 and 7 is provided with a transverse opening 35, in register with an opening 23 when the frames '66 and 7-7 are in normal position, and a pulley 36 is journaled in each opening. The cords 33 pass from the weights 34: over the pulleys 31, and through an opening 35 and over a pulley 36 in the opening, to a connection with the stile of a sash 16 or 17.

The cross piece 6 of the frame 66 is provided with a rib or stop 37 engaging a rabbet in the cross bar of the casement, for making a tight joint. The sashes may be pulled inwardly and separated, as shown in Fig. 1, for the purpose of cleaning or repairing, or may be moved into the normal position of Fig. 2, and locked in such position.

When in normal position the grooves of the frames 66 and 77 register with the grooves 4, so that the sashes may be moved upwardly or downwardly, as in the ordinary form of window construction. To bring the sashes into position for cleaning, the latch 21is first released, and both frames are swung inwardly. The outer surface of sash 16 is now accessible. Latch 19 is then the sashes and a frame for each sash in the upper end of the easement, said casement being recessed to receive the frames, each frame having a rabbet at its inner side to receive the sash, the outer frame being hinged to the easement to swing outwardly at its upper end, and the inner frame being hinged at its lower end to the outer frame.

2. The combination with the sashes and the window casement having its top recessed on its inner face at the inner side thereof, and having the inner face of each side member recessed at its upper end and at the inner side, and having a transverse shoulder at the lower end of each recess, a pair of substantially U-shaped frames seated in the recess, the outer frame being hinged to the inner ends of the shoulders and the inner frame being hinged at its lower ends to the lower ends of the outer frame, the sides of the easement having grooves for the sashes at their lower ends, and each frame having a rabbet at its inner side for a sash, each rabbet registering with a groove at the lower end of the easement, and a sash movable in each groove.
